BRICK-MOLDING MACHINE.

Specification of Letters Patent.

Patented Sept. 26, 1905.

Application filed July 25, 1904. Serial No. 218,080.

To all whom it may concern:

Be it known that I, LEVI SHELL, a citizen of the United States, residing at Sibley, in the county of Osceola and State of Iowa, have invented a new and useful Brick-Holding Machine, of which the following is a specification.

This invention relates to an improved brickmachine, and has for its object to provide an inexpensive, durable, and eflicient machine of this character by means of which bricks, tiles, building-blocks, and similar articles may be conveniently and rapidly manufactured.

A further object of the invention is to provide a tamping-carriage mounted on the bed of the machine and movable to operable position above the mold-box, so that after the mold-box has been filled the cement, concrete, or other material may be thoroughly tamped and the carriage withdrawn to permit the removal of the molded product.

A still further object is to provide the mold box with a plurality of division plates or partitions, so that a number of bricks or tiles may be formed at each operation of the machine, and, further, to provide means for ejecting said bricks or tiles without chipping or otherwise injuring the same.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes in form, proportion, and minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

In the accompanying drawings, forming a part of this specification, Figure 1 is a perspective view of a. brick-machine constructed in accordance with my invention and showing the tampingcarriage in position over the mold-box. Fig. 2 is a longitudinal sectional view. Fig. 3 is a transverse sectional view. Fig. i is a perspective view of one of the mold-trays detached. Fig. 5 is a perspective view of a portion of the machine, showing the mold-tray removed. I

Similar numerals of reference indicate corresponding parts in all the figures of the drawings.

In constructing the machine I provide a supporting frame or table formed of wood, metal, or other suitable material and consisting of the uprights 5, to which are bolted or carriage 27.

otherwise rigidly secured longitudinal beams 6. Secured to the uprights 5 is the table-top 7, having a rectangular opening 8 formed therein, as shown, and disposed beneath said opening and supported by a horizontal bar 9 is the mold-box 10. The mold-box 10 is provided with a series of division plates or partitions 11, the ends of which are spaced from the side walls of the box, as indicated at 12, and slidably mounted in said box is a removable tray 13, which forms the bottom of the mold, as shown. The tray 13 is provided with a plurality of spaced openings 14, adapted to receive the division plates or partitions 11, so that when said tray is in position the box will be divided into a series of molding chambers 0r compartments 15. designed to support the bricks or tiles after the latter have been ejected from the moldbox, as clearly shown in Fig. 3 of the drawings, said tray being provided with a removable front wall 16 and removable rear and end walls 17, so as to permit the bricks to be readily detached from the tray without chipping or otherwise marring the same.

Slidably mounted in suitable guides 18 are plungers 19 for elevating the tray 13 and ejecting the bricks from the mold-box, said plungers being connected by a horizontal baror rod 20 and operated through the medium of a foot-lever 21, pivoted, as shown at 22, to one of the longitudinal beams of-the supporting frame or table. The plungers 19 are also connected by a brace-rod 23 to the foot-lever 21, and are each provided with spaced ejectingrods 19 and a laterally-projecting block or stop 24, which engages a cross-bar 25 and serves to limit the downward movement of said plungers.

Secured to the rear end of the supporting frame or table are brackets 26, upon which is mounted for travel a reciprocating tamping- The carriage consists of a horizontally-disposed bar 28, to which is pivoted, as indicated at 29, a pair of rearWardly-extending inclined bars 30, the opposite ends of which are rigidly recured to a bar or axle 31, provided with terminal wheels or rollers 32. The Wheels or rollers 32 travel in grooves or guides 33, formed in the brackets 26, so as to permit the carriage to be moved forward over the mold-box when filling the latter, as will be more fully explained hereinafter. The

horizontal bar 28 is provided With terminal iandle's 3d and a plurality of intermediate tamping teeth or plungers 35, corresponding The tray 13 is in number to the molding chambers or compartments 15, so that when the carriage is moved forward to a position directly over the mold-box and the bar 28 swung downwardly on its pivotal connection one tooth will enter each of the molding-compartments and thoroughly tamp the cement, concrete, or other material contained therein. The tampingteeth or plungers 35 are provided with enlarged heads 36 and reduced threaded extensions 37, which enter openings formed in the bar 28, and are rigidly secured therein by clamping-nuts 38. The tamping-carriage is pivoted on the wheels or rollers 32 of the axle 31. and a brace-bar 39 preferably connects said axle and the inclined bars 30 in order to insure additional rigidity to the frame of said carriage. The rear uprights 5 are preferably extended a short distance above the table-top, as indicated at 40, to form a rest or support 41 for the horizontal bar 28, so that when the carriage is moved backward and the terminal handles 34 brought into engagement with said uprights the tamping-carriage will be supported in inoperative position, thereby permitting the bricks to be readily ejected from the mold-box.

In operation the tray 13 is introduced in the mold-box and the compartments formed by the division plates or partitions partly filled with cement, concrete, or other material of which the bricks are to be formed. The tam ping-carriage is then moved forward to a position directly over the mold-box and the concrete thoroughly tamped in the several compartments by reciprocating the bar 28 on its pivotal connection, after which more concrete is introduced in the compartments and the tamping operation continued, the surplus material being subsequently removed with a trowel or straight-edge in the usual manner. The tamping-carriage is then moved rearwardly and the bricks ejected from the mold by depressing the foot-lever, which operation elevates the tray to the position shown in Fig. 3 of the drawings. The removable side and end pieces of the tray are detached and said tray placed upon a table or other suitable support designed to receive the same, after which a pallet is placed upon the top of the bricks and the tray reversed, leaving the bricks on the pallet and in position to be removed to the drying-racks until sufficiently hard for use.

If desired, the bricks or tiles may be formed with an exterior finish in imitation of chipped rock or other ornamental designs by inserting a pattern-plate in the bottom of each of the molding-compartments, as will be readily understood.
